Alpine summer, Scottish winter, Autumn on the gritstone… Those merino sheep have catering for every climate down to a T.

We use 100% genuine 160gsm New Zealand merino wool to ensure our Kepler long-sleeved top earns its place in everyone's outdoor layering system.

A staple in most people's layering systems, Kepler fits right in there with excellent performance over a vast range of conditions and is, quite simply, a garment that does many things really rather well.

Breathable, wicking, fast drying, and famously odour resistant, Merino can be worn in the hot, in the cold, in the wet, and in the dry: for all round comfort over extended durations, merino is our baselayer of choice.

Thumb retainers in the cuffs keep the sleeves where they're meant to be, ensuring that your wrists are protected from the cold - pretty useful when your activity involves a lot of reaching.

Flatlock seams and an anatomical cut enhance the natural next-to-skin comfort of merino. Kepler is designed to have a flattering fit that isn’t too ‘base layery’, so you’ll fit right in at the pub after a day on the hill.

With thermoregulatory and anti-microbial properties, merino wool is more than a match for day-in, day-out use across the temperatures in changeable mountain conditions, help you to stay fresh, comfortable, and protected no matter what the weather decides.

Getting another one as soon as I can

Mine got slightly smelly after 3 weeks of constant use in the Himalayas. I'd have hated to have smelled some of the poly thermals my friends were wearing

Kepler merino base layer

I wore my Kepler long sleeve top last Saturday 3rd June for the Lyke Wake Walk - 42 miles across the North York Moors. It did what it says it will do... kept me warm in the cool morning (2am start) and was cool when the day got hot, which it did. No chafing, no rubbing, and no ponging after a solid 18 hours effort (we weren't quick!). Great piece of kit. Keep up the good work!

Revewe

I've tried merino tops before, and this is the only one that doesn't feel like wool - this really feels (and looks) more like soft cotton. Used in July heat and November chill. If I do wash it it's usually to get stains from Chinese food or beer out of it, not because it stinks. Use the 'hand wash' proggie on the machine at 30°c and air dry. 1-3 weeks of running, hiking and casual wear without a wash is no problem at all. Generously sized.

Brilliant piece of clothing!

New customer to Alpkit and this was my first purchase ahead of a trip to Iceland.

Just returned from those 10 days in Iceland and I wore the top constantly whilst trekking the interior. Worked brilliant all the time, soft and warm and not pongy as far as I could smell!

Back to order a couple more in the new year as a go-to top for daily use it was that impressive.

Very warm and snuggly

Very pleased with my new base layer, I am 6'2" with a 40" chest and the Medium is ideal - thanks Alpkit

Great bit of kit

Really good piece of kit. Very comfy and warm. Love the feature of the thumb holes and long sleeves. My only issue with it is the neck line is super wide and leave a lot of skin exposed. I'd like it to be higher/ tighter, so I don't have to wear a second layer underneath to close the gap.

Quality baselayer

Lovely, comfy, quality baselayer, does exactly what it's supposed to.
My only slight quibble it's it a tiny bit shorter in the body than I would prefer. To be clear it's not too short, rather just long enough. I'm 5,10" and not especially broad. I usually wear a medium in outdoor/mtb kit so might be worth sizing up to a large if you're on the cusp and you prefer a longer cut.
I've got the blue and grey one with a subtle logo and the colours look great in the flesh.

Overall I'm very happy with it!

The rest is ok, no smell for days

Second Summit Kepler Review

Second Summit put Kepler to the test

Hard to beat for the money. Well made, warm, dries well, comfortable and stays odour free. Great product from Alpkit, and one that would be well used on multiday trips. Order a size down if you like athletic fit.

Wild Running Top Mens Winter Running Gear

Sim Bensons ideal winter running gear

Merino wool base layers are normally the warmest, and as long as they are ethically produced you can feel happy wearing a natural fibre. I wear either my Alpkit Kepler (RRP £29) or my Howies short-sleeve base layer (RRP £45) pretty much all the time. They look great as well as performing brilliantly in all but the warmest weather. Synthetic base layers dry faster than Merino, but Merino retains its warmth even when wet

Women Climb Kepler Merino Top Review

I love the design of this women specific base layer top. It looks as good on its own after a hard day of climbing as it does at the crag under all your layers. The people at Alpkit have clearly thought about every aspect of this garment and tested it out to create a beautifully designed and functional garment that is perfectly fit for purpose
